SQLBase .NET DataProvider Connection Problem

I'm having difficulty connecting to an SQLBase database (1-user Licence SQLBase v. 7.5.1). I'm trying to use the latest .NET DataProvider (from Gupta, installed "typically") to no avail. I have referenced the Gupta.SQLBase.Data dll.

The following is my code:

using System;
using System.Collections.Generic;
using System.Text;
using System.Data;
using Gupta.SQLBase.Data;

namespace ConsoleApplication1
{
   class SQLConnect
   {
      static void Main(string[] args)
      {
         string ConString = "DataSource=C:\\ADP\\SQLBase\\pay5win\\PAY4WIN.DBS;UserId=SYSADMIN;Password=master;";

         SQLBaseConnection AdpCon = null;

         try
         {
            AdpCon = new SQLBaseConnection(ConString);
            AdpCon.Open();

            Console.WriteLine("The Connection Opened!");
         }
         catch (Exception e)
         {
            Console.WriteLine("Error: " + e + "- " + e.Message.ToString());

         }
         finally
         {
               AdpCon.Close();
          }
      }
   }
}

The output:

ERROR: System.DLLNotFoundException: Unable to load SQLBASEUTIL.dll driver library.
Please check your CLIENTRUNTIMEDIR entry inside INI file or check your environment variable path or system path.

SqlBaseUtil.dll is in the folder it was installed to. What am I doing wrong?

Thank you!
